Here's one of my favorite EddyStone Communications receiver,  Model EC10.

These are a very nicely engineered bit of kit. This particular EC10 has the battery pack adapter, which are usually very hard to find these day.

However this can be swapped out for the mains adapter pack, which sits in the same slot in the back.

Everyone should have at-least one EddyStone receiver in their shack or collection.

MF and Full HF coverage over 5 bands. AM,CW and SSB modes.
